The cationic poly[ tris( trimethylsilyloxy) silyl] propyl methacrylate ( PTRIS) emulsion was syn-thesized with 3-[ tris( trimethylsilyloxy) silyl] propyl methacrylate ( TRIS) as materials, AIBA as an initiator, OATAC and OP-10 as a composite emulsifier by pre-emulsified polymerization. Effects of pre-emulsified poly-merization on the particle diameter and stability of the emulsion were discussed. Effects of dosages of initiator and emulsifier, reaction temperature and time on the property of silicone emulsion were also discussed by or-thogonal test. The obtained polymer emulsion was then characterized by IR spectroscopy and its surface per-formance was analyzed as well. Results showed that monomer emulsion with the particle size of 229. 4 nm could be prepared by mechanical agitation and ultrasonic homogeneity for 30 days without layers. By orthogo-nal test, the optimum synthesizing condition was obtained as follows:the dosage of initiator was 0. 75 wt% and emulsifier was 3 wt% of the monomer, the reaction temperature was 75℃, and the reaction time was 4 h. The polymer emulsion obtained under this condition was uniform without gel in appearance, had good stability, with conversion rate of 94. 80%, the average particle size of 357. 5 nm, dispersion coefficient of 0. 145, and Zeta potential of 20. 2 mV. The cotton fabric modified by PTRIS emulsion exhibited an excellent water and oil repellent performance with the water contact angle of 135 ° , the contact angle to methyl iodide of 117 ° , and the surface energy of 3. 82 mN/m.
